Abstract
The invention relates to a protein-radical biogum fiberboard and a manufacturing method thereof. As the protein radical biogum fiberboard adopts formaldehyde-free protein radical biogum as an adhesive, the formaldehyde emission is far less than that of board products manufactured by urea-formaldehyde glue or phenolic glue. The advanced manufacturing method ensures that the boards produced have excellent hydrolytic resistance and can effectively avoid phenomenon of delamination or barbotage of the boards.
Description
Technical field
The present invention relates to a kind of protein-radical biogum fiberboard and manufacture method thereof, belong to wood-based plate and make the field.
Background technology
Traditional fiberboard makes the problem that product usually exists formaldehyde to exceed standard health to be constituted grave danger owing to adopt adhesive made of synthetic resin (as urea-formaldehyde glue, phenol glue) to come binder fibre.For this reason, in recent decades, many countries are all in the research of carrying out protein-radical biogum fiberboard energetically, to replace traditional synthetic resin fiber plate.Yet,, hinder its popularization because problem such as protein-based adhesive exists that adhesive strength is low, poor water resistance, antimicrobial degradation capability are low makes it can not reach industrial application requirements well.Therefore, how to develop the emphasis that performance excellent protein radical biogum is this area research always.
2002, USDOE has subsidized a huge plan of being undertaken by the cooperation of how tame research institution, purpose is to improve the 26S Proteasome Structure and Function of soybean protein radical biogum, thereby improve the performance of soybean protein radical biogum and improve the adaptability (as dispersibility, active phase, miscibility etc.) of soybean protein radical biogum mask-making technology, the production and processing mode of developing low-cost is beneficial to the large-scale production of soybean protein radical biogum.Compare with the traditional bean gum that uses in the past, the modification bean gum is greatly improved in performance, and range of application is also in continuous expansion.But compare with adhesive made of synthetic resin (as urea-formaldehyde glue), still there are the problems such as requirement that resistance to water is weak, medium density fibre board (MDF) thickness swelling rate that produce can not reach CNS in the modification bean gum.Therefore, that both at home and abroad generally uses now remains various urea-formaldehyde glue fiberboards, without any a tame enterprise can be in enormous quantities, industrialization ground protein-radical biogum producd fibers panel products.
